1.) what is the minimum number of bits required to represent -3,997 using 2's complement form?
lisabon 2012 [21]

The binary representation of +3997 is 1111 1001 1101.

In one's complement this is simply adding a sign bit and inverting all the bits:

1 0000 0110 0010

The two's complement is the one's complement plus 1:

1 0000 0110 0011

That's 13 bits. Normally the sign bit would be at an 8, 16 or 32,... bit boundary.

For -436 it's 10 0100 1100 and 10 bits

\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\

Explanation:

It is easy to understand. Algorithm is a step-wise representation of a solution to a given problem. In Algorithm the problem is broken down into smaller pieces or steps hence, it is easier for the programmer to convert it into an actual program

Algorithms are time-consuming. Big tasks are difficult to put in algorithms. Difficult to show branching and looping in algorithms. Understanding complex logic through algorithms can be very difficult.
